Description

Technical Field

[0001] The utility model relates to the technical field of clamping seat type chucks, in particular to a chuck with a protective structure. Background Art

[0002] A clamping chuck is a mechanical device used to hold a workpiece so that it can remain stable during processing. It consists of a base and a clamp that can hold the workpiece and tighten or loosen it by adjusting the screw of the clamp. A clamping chuck is usually used on machine tools to clamp rotating workpieces such as steel pipes and shafts. It has the characteristics of simple structure, easy operation, and strong clamping force, and is widely used in mechanical processing, lathe processing and other fields.

[0003] Since the clamp-type chuck is an important part of mechanical equipment, if it is not protected, it may be damaged or malfunction, affecting normal production and work. The existing protection method is usually to install a protective cover on the surface of the base to protect the clamp-type chuck to ensure the safety of workers and workplaces. The protective cover is usually installed with bolts. When the chuck is repaired and lubricated regularly, the protective cover needs to be disassembled. Frequent disassembly will cause scratches on the threads, which will cause the protective cover to loosen during the protection process. To address this problem, we propose a chuck with a protective structure. Utility Model Content

The folding rod 873 fixed on the surface of the protrusion 874 is folded on the surface of the support block 872. The movable rod 875 fixed on the surface of the movable plate 85 drives the protective cover 4 to move, and the protrusion 874 also moves from the tip of the heart-shaped groove 86 to the recess, completing the fixation of the protective cover 4. This method can facilitate the operator to repair the chuck 1 and prevent non-operating personnel from opening the protective cover 4.

[0025] A through hole 5 is provided on the surface of the fixed column 3, and the provision of the through hole 5 can ensure the stable movement of the moving rod 875. An arc groove 6 is provided on the surface of the fixed column 3, and the provision of the arc groove 6 can limit the movement of the fixed rod 81. A transverse groove 7 is provided on the surface of the fixed column 3, and the provision of the transverse groove 7 can ensure the stable movement of the round rod 84. The cross-sectional shape of the protective cover 4 is a hollow semi-cylindrical shape, and the hollow semi-cylindrical protective cover 4 is more closely matched with the shape of the clamping seat chuck 1. The protective member 87 includes a spring 871, one end of which is fixedly mounted on the surface of the moving plate 85, and the other end of which is fixedly mounted on the surface of the support block 872.
